September might be my favorite travel secret. While everyone stresses about going back to school, I’m over here finding flights so cheap I had to double check they weren’t mistakes.

Whether you’re craving one last splash of summer or ready to embrace early fall vibes, these 12 destinations are calling your name.

Cheapest Places to Fly in September 2025

Looking for the cheapest places to fly in September 2025? Visit Mexico City, Mexico for its rich history and vibrant street food, explore Cambodia for stunning temples and cultural landmarks, relax in the Caribbean with its pristine beaches and crystal-clear waters, and discover Hungary for its historic architecture and thermal baths. Whether you’re interested in history, culture, or cuisine, here are the top budget-friendly destinations to visit in September 2025.

1. Mexico City, Mexico ($250–$450 roundtrip)

• ✈️ Flight Time: 3-5 hours (from major US cities)
• 🛫 Airlines: Aeromexico, United, Delta (usually nonstop or with 1 stop)
• 🔥 Perfect for: Culture lovers 🏛️, foodies 🌮, history buffs 📜, budget travelers 💰

Mexico City is the ultimate fall getaway that won’t wreck your bank account. Think amazing museums, lively plazas, and killer architecture without the insane prices of typical fall hotspots.

Zócalo Plaza has legit street food that’ll blow your mind, and the National Museum of Anthropology is actually interesting with all those Aztec and Maya artifacts (worth every penny of the entrance fee). Wanna get artsy? Frida Kahlo’s Blue House is a total vibe. And if you need a break from the city hustle, Chapultepec Park is where locals chill with epic castle views.

Let’s be real, you won’t see everything in a weekend. This city has layers, from hidden mezcal bars to local mercados that most tourists never find. September is clutch for visiting. No crowds, temps around 75°F, and you might catch some Independence Day decorations.

For the cheapest flights, Book 3-4 months ahead and fly midweek. Aeromexico often includes a checked bag, while United and Delta usually match fares when sales drop. Watch for flash deals in late spring.

Siem Reap is the perfect budget-friendly fall destination for anyone craving an epic adventure without the massive crowds. The rainy season wraps up in September, leaving everything lush and green, with way fewer tourists blocking your perfect shots.

Angkor Wat is obviously a must-see (it’s on Cambodia’s flag for a reason), and exploring the massive temple complex when it’s less crowded is an absolute game-changer. Don’t skip Ta Prohm where massive tree roots are literally devouring ancient temples, or Bayon Temple with those massive stone faces staring at you from every angle. The Night Market comes alive after dark with insanely cheap street food and souvenirs that’ll make your friends jealous.

The best part? Fall visits mean you can actually get those iconic sunrise photos at Angkor without fighting through hundreds of selfie sticks. Plus, temperatures cool down from the brutal summer heat, making temple hopping actually enjoyable instead of a sweaty mess.

Flights are often cheapest with Asian carriers like Korean Air or EVA Air, especially if you’re flexible with layovers.

Curaçao is that under-the-radar Caribbean gem you’ve scrolled past on Instagram. Fall is the ultimate time to visit this colorful island since it sits outside the hurricane belt, making it one of the few Caribbean spots that’s actually safe and cheap to visit in September.

Willemstad will blow your mind with those candy-colored Dutch buildings lining the waterfront. Just across the floating bridge, Mambo Beach offers crystal clear waters perfect for swimming without the usual summer crowds. Snorkeling at Playa Lagun puts you face-to-face with sea turtles without expensive tour bookings, and Shete Boka National Park has those dramatic ocean sprays against limestone cliffs that’ll rack up the likes on your feed.

Budapest is basically Europe’s best-kept secret for fall travel, with prices that’ll make you wonder why everyone’s fighting crowds in Paris and Rome. September brings perfect sweater weather, golden light for photos, and way fewer tourists at all the main spots.

The Danube River splits the city into Buda and Pest, with the hilly Buda side offering insane panoramic views from Fisherman’s Bastion that look straight out of a fairytale. On the Pest side, the massive Parliament Building is even more stunning when lit up at night. Don’t miss soaking in the Széchenyi Thermal Baths, where locals and travelers chill in steaming outdoor pools even as the fall air gets crisp.

Jet-setting to Hungary doesn’t have to destroy your savings account. Flights from the East Coast often dip under $500 roundtrip with LOT Polish via Warsaw. Lufthansa also runs fall sales through Frankfurt or Munich. Book 3–4 months ahead and aim for midweek departures to maximize savings.

Prague is that European city that looks like it was literally built for fall. September brings cooler temperatures, way fewer tourists, and this magical golden light that makes the already stunning city look like something out of a storybook.

Charles Bridge at sunrise is something else when the morning mist rises off the Vltava River, and you can actually take photos without elbowing through summer crowds. The Prague Castle complex dominates the skyline from any angle, while getting lost in the winding streets of Old Town leads to hidden courtyards and local pubs that tourist guides don’t mention. Don’t skip Letná Park where locals hang out with beers watching the sunset over the red rooftops below.

Getting to the Czech Republic is surprisingly affordable if you plan it right. Flights from the Northeast often dip under $500 with British Airways via London, while Midwest travelers can go for Lufthansa. West Coasters can score Delta flash sales if they book 3-4 months out.

Barcelona is the perfect blend of beach city and cultural powerhouse with direct flights that won’t destroy your bank account. This Catalan capital has mind-blowing architecture, killer food, and beaches right in the city.

La Sagrada Familia will blow your mind no matter how many photos you’ve seen of it, but visiting in fall means you’ll actually get tickets for your preferred time slot. Wandering through the colorful mosaic wonderland of Park Güell without summer crowds feels like you’ve discovered a secret, while the narrow medieval streets of Gothic Quarter come alive with local energy once the cruise ships leave port. Beach day? Barceloneta is still totally doable in September, minus the intense crowds and scorching heat.

The fall magic of Barcelona comes from actually being able to enjoy the city like a local. The weather is perfect, the crowds clear out, and the hotel rates drop dramatically.

Lisbon is that European capital that somehow still flies under the radar for fall travel, which means you get all the charm without the crazy prices. In September, the weather stays sunny and 75°F, crowds thin out, and you can explore the city’s steep hills without sweating through your shirt.

Alfama district feels like stepping back in time with its narrow winding streets and authentic family-run tascas serving up grilled sardines. The São Jorge Castle rewards your uphill trek with panoramic views of the city’s red rooftops against the blue Tagus River. And don’t miss riding the vintage Tram 28 that rattles through the most scenic neighborhoods.

Provincetown at the tip of the Cape has an artsy, laid-back atmosphere with colorful shops along Commercial Street and amazing seafood shacks where locals actually eat. The Cape Cod National Seashore offers miles of pristine beaches and hiking trails without the summer parking nightmares. Checking out the Chatham Lighthouse is way more peaceful now, and whale watching tours from Hyannis are actually better in fall when the whales are more active before migration.

Getting to the Cape is super affordable in the fall. JetBlue often runs roundtrip deals under $200 from East Coast cities like New York and DC. If you’re flying from the Midwest, keep an eye out for Delta flash sales through hubs like Detroit and Minneapolis.
